Hobbing cutter and method for processing shaver by using said hobbing cutter

Abstract

The present invention provides a hobbling cutter with many cutting teeth, which comprises a first tooth part that can form a first involute profile on a workpiece and a second tooth part that can form a curve profile on the workpiece. By using the hobbling cutter, the present invention provides a method of forming a shaving tool whose procedures are as following: a first involute path and a curve profile are arranged at an appointed point on the workpiece that is prepared to be processed, which makes an angle formed by a rotation axis of the hobbling cutter and a rotation axis of the workpiece mentioned-above; the workpiece that is prepared to be processed is hobbled by the hobbling cutter in direction of a cutting path; a cutter provided with the first involute profile and an escaping area profile is formed by the first and the second tooth parts.

Description

technical field [0001] The present invention relates to a gear hobbing cutter and a method for forming a gear skiving cutter, in particular to a gear hobbing cutter formed by cutting teeth with two different profile configurations and using the gear hobbing cutter to process a gear with an involute A gear hobbing cutter in the escape area of ​​the skiving tooth and the root of the skiving tooth and a method for processing the skiving knife by using the hobbing knife. Background technique [0002] The traditional cutting of gears is to cut the tooth shape by the movement of the workpiece and the tool. First, the hobbing cutter in the shape of a worm is used as a semi-finishing cutter, and then the gear is finished by a gear scraping cutter with a gear shape. Please refer to the figure As shown in 1, the figure shows the appearance of a traditional gear scraping knife. The gear skiving knife 10 has a disc-shaped body 11, and scraper teeth 12 are arranged on the outer periphery...

AI Technical Summary

Problems solved by technology

[0004] 1. The diameter d1 of the drill hole 131 is greater than the root distance d2 of the scraper teeth 12, so that the scraper teeth 12 form a thinner neck 122. The existence of the neck 122 reduces the strength of the scraper teeth 12, and the neck 122 is easy to cause fracture

[0005] 2. After the main body 11 has been drilled and moved to the gear hobbing machine, it must be aligned before the gear can be hobbed accurately, which is labor-intensive and time-consuming

[0006] 3. Drilling machine and gear hobbing machine must be installed, the equipment cost is high and takes up space

[0007] 4. The main body 11 is bulky and heavy. It is extremely inconvenient to move up and down between the drilling machine and the gear hobbing machine. It consumes manpower and man-hours, and it is easy to damage the main body due to collision.

However, in the existing technology, the skiving cutter in Fig. 3 mainly utilizes two gear hobbing processes to form two different curves 141, 142. However, such a process is time-consuming in the processing procedure and virtually increases production. Cost and Manpower Consumption
